1. A system for increasing an indoor pressure of an air mobility comprising:
a refrigerant line, through which refrigerant is circulated and which includes a compressor, a condenser, an expander, and an evaporator;
a first air line, which is connected to the refrigerant line upstream of the compressor via a first valve, branches therefrom, and is connected to an outside;
a second air line, which is connected to the refrigerant line downstream of the compressor via a second valve, branches therefrom, and is connected to an indoor space;
a third valve, which is provided at the second air line to allow the refrigerant or air that flows in the second air line to selectively flow to the outside or the indoor space; and
a controller, which, when a state of the air mobility is abnormal, is configured to operate the first and second valves to allow outdoor air to flow into the first air line, the refrigerant line, and the second air line by virtue of activation of the compressor and operate the third valve to allow discharging of the refrigerant to the outside and then to allow the outdoor air to flow into the indoor space after completion of the discharging of the refrigerant.
